Subject: MdeModulePkg:Create gEdkiiVariableRuntimeCacheInfoHobGuid

Install the callback of gEfiPeiMemoryDiscoveredPpiGuid
to create gEdkiiVariableRuntimeCacheInfoHobGuid in
VariablePei module. When PcdEnableVariableRuntimeCache
is TRUE, the callback will be installed to allocate
the needed buffer for different type variable runtime
cache, unblock the buffer and build this HOB. Then the
runtime cache buffer address and size will be saved in
the HOB content.
